A CORPORATION OF MASSACHUSETTS MECHANISM non. TEAN'SFERRING KNITTED wnns Application filed December 14, 1922, Serial No. 666 787. Renewed September 27, 1927.

This invention relates to knitting and more particularly to the transfer of knitted webs.

An object of the invention is to provide improvements in that type of stitch transferring device shown and described in my application for United States Letters Patent filed February 23, 1923, bearing Serial No. 620,587 and which consists, briefly, of mechanism designed to apply a transfer ring to the needles of a circular knitting machine for the purpose of transferring the stitches from said needles to the points of the ring, so that the knitted web may be removed with said ring; or for the purpose of transferring stitches from the points of the ring to the needles. In the operation of transferring knitted web, as conducted with the mechanism shown in the said application, the ring is placed in a ring carrier and the latter automatically swung to position to cooperatively register the points of the transfer ring with the needles. After the desired transferof stitches is effected the ring car rier is swung away, and the ring left in position upon the needle bed to be removed by hand.

The improvements contemplated by the present invention are, first; to construct the ring carrier and its operating mechanism so that after the stitches have been properly transferred from the needles to the points of the ring, or vice vei'sa, the point ring is removed from the needle cylinder automatically by its carrier. Second; to provide improved mechanism for moving the yarn guide ring of the knitting machine out of the way of the point ring to enable application of the latter to the needles, and third; to provide a construction that will permit my invention to be used in connect-ion with a knitting machine equipped with a ribbing or welting dial.

These objects I accomplish in the manner hereinafter set forth, reference being had to the accompanying drawings, in which I illustrate, for example, mechanism employed when transferring stitches from the needles of a knitting machine to the points of a transfer ring.

In the drawings, Fig. I is a view in elevation of part of a circular knitting machine showing my present invention. In this view, the point ring is shown in section and as supported by its carrier in idle position.

Fig. II is similar View showing the carrier swung to register the points of the ring with the needles.

Fig. III is a similar View showing the point ring lowered to impale the stitches upon the needles.

Fig. IV is a plan view of the knitting machine and the parts of my invention showing the latter in the positions assumed in Fig. II.

Fig. V is a View of the machine in end elevation, and partly in section, illustrating my improved yarn guide ring operating mechanism and the embodiment of my invention in a knitting machine equipped with a dial.

Fig. VI is a View similar to Fig. V but illustrating another means for moving the yarn guide ring to one side; and,

Fig. VII is a View in sectiontaken on the line VIIVII of Fig. V showing a locking disc for the transfer mechanism of a rib machine.

Proceeding to a detailed description of the mechanism and referring to Figs. IIV inclusive, the needle cylinder 1 is rotatably mounted on the bed plate 2, to which the bracket 3 is secured, the latter affording support for a post 4 which provides bearing for a horizontal rock shaft 5. At the outer end of this shaft 5 there is mounted in fixed engagement a spur pinion 6 which inter-meshes with a gear sector havingan angularly directed arm 8, the sector being loosely mounted upon a horizontal shaft 9. An anti-friction roller 10 is carried by the arm 8 and rides in a peripheral cam slot 11 formed in a cam drum 12 adapted to rotate about a vertical axis under intermittent actuatiori. This cam drum 12 is provided with two other cam slots 14.- and 15, for a purpose to be presently noted.

Fixedly mounted upon the rock shaft 5 is a bell crank, the arm 16 of which serves to support the point ring carrier, which comprises a circular holder 17 with which the arm is formed, and a sleeve 18, slidably and rotatively held within the holder 17 and in turn adapted to slidably receive the point ring indicated comprehensively at 19. Ordinarily the sleeve 18 is locked against rotation by means of a lug 20 secured to the holder 17 and against sliding movement by means of a spring pin 21 mounted upon the said holder 17. Thus roper initial alignment of the elements is insured.

The oint ring 19 is applied to the carrier when t e latter is in the retracted position shown in Fig. I. When the knitting operation is completed, rotation of the cam drum 12 is begun, the action of which is to swing the sector 7 with consequent partial rotation of the pinion 6 and turnin of the shaft 5. The point ring carrier is t ereby swung to the position shown in Fig. II with its points 22 registering with the needles of the cylin der 1. The bell crank of which the arm 16 constitutes a part includes an arm 23 which carries a laterally projecting pin 24. \Vhen in this osit-ion the pin 24 is located directly above t e upper end of a rod 25 the lower end of which is operated by the slot 15 in the cam cylinder 12. This rod 25 is raised by the action of the cam slot 15 to the position shown in Fig. III so that its upper end bears firmly against the under face of the pin 24 thereby serving to lock the point ring carrier securely in position against backward yielding. The carrier is limited in its downward movement by engagement of a laterally protruding finger 26-carried by the holder 17-with the upper end of a post 27 which projects upwardly from the bed plate 2 of the machine.

Rotatably mounted in the arm 16 is a shaft 28 having one of a pair of arms 29 secured to each end forming a yoke which embraces the holder 17. One arm 29 is extended at 30 to carry a pin 31. Projecting inwardly from the yoke terminals 29 are pins 32 which pass through slots 33 in the sides of the holder 17 and enter an annular groove 34 in the outer face of the sleeve 18.

\Vith the point ring carrier in the position shown in Fig. II the pin 31 on the extension 30 is lodged in a laterally recessed head 35 formed on the upper end of a rod 36, the lower end of which is operated by the slot 14 in the cam drum 12. Under the action of this cam slot 14 the rod 36 is raised to the osition shown in Fig. III, rocking the sha t 28 and lowering the yoke arms 29, which act through the pins 32, to carry the sleeve 18 down, thereby releasing said sleeve from the retaining action of the lug 20 and spring pin 21. As the point ring 19 is carried by the sleeve 18 it also moves downwardly, and its points 22 are caused to impale the stitches on the needles of the cylinder 1 as shown in Fig. III.

The needle cylinder 1 is then rotated for the purpose of retracting the needles so as to leave the stitches upon the points 22 of the point ring 19, this ring rotating with the needle cylinder 1 and the sleeve 18 rotating with the point ring 19. Vhen this period of rotation is completed and the stitches are transferred, the rod 36 is depressed by action of the cam slot 14. raising the sleeve 18 without disturbing the holder 17, and consequently lifting the point ring 19 from the needle bed of the machine. The rod 25 is then depressed by the cam slot 15, to release the pin 24 and permit the cam drum 12 to act through the medium of cam slot 11 and gear sector 7 with correlated parts to swing the point ring 19 back to the position shown in Fig. I, carrying upon its points the stitches of the knitted web for the purpose of subsequent handling. The transfer or point ring 19 is held against accidental dislodgmcnt from the sleeve 18 by means of a spring catch 37 pivotally mounted upon said sleeve and entering a notch 38 in the point ring.

Forming part of the transfer or point ring 19 is an annular stripping element 39 having radial fingers which extend outward between the points 22. The stripping elc ment 39 is carried by rods 40 which slide in the point ring 19 and are connected at their inner ends to an annular member 41 en gaged by a thrust rod 42 which has bearing in the sleeve 18 and is connected at its outer end to an arm 43 pivotally mounted between spaced extensions of the bell crank arm 16. The thrust rod 42 is maintained firmly in contact with the member 41 by means of a spring pressed finger 44, which is pivotally mounted upon the arm 16 of the carrier bell crank, and it engages a notch in the fulcrum boss of the arm 43. The parts remain in this position during movement of the carrier from the position of Fig. I to that shown in Fig. II; but when the rock shaft 28 is turned to move the sleeve 18 and point ring 19 to the position shown in Fig. III driving the points 22 downward beyond the fingers of the stripping element 39 and impaling the stitches on the needles. the spring finger 44 is released from the notch 45 in the boss of arm 43 by means of an actuating lug 46 on the lever extension 30, as shown in Fig. III. The arm 43. under the influence of a spring located therebencath is forced upwardly, withdrawing the thrust rod 42 from contact with the annular member 41; consequently, when the point ring 19 is raised from the needle bed, the eh ment 39 will not be projecting and there will. be no possibility of the stitches becoming dislodged from the points 22 of the ring 19. The friction between the rods 40 connecting the stripping element 39 and the annular mem' ber 41, and the channels in which said rods slide is such as to retain the stripping ele ment 89 in any position to which it is moved. After the point ring 19 with the web upon it has been removed by releasing the catch 87-from the carrier sleeve 18 preparatory to the application of another ring thereto,

the spring finger 44 is reset so that it enters the notch 45 in the fulcrum boss of arm This is conveniently effected by means of a handle 47 integrally formed with the arm 43. It will thus beseen that the operation of the machine is entirely automatic, the empty point ring 19 being applied to the carrier sleeve 18 while the latter is in the position shown in Fig. I and later removed therefrom when said ring is returned to such position; the stitches previously on the needles of the machine being then impaled upon the points 22 of said ring.

Before the point ring 19 can be applied to the needles it is necessary that the yarn guide ring indicated at 48 be moved out of the way; and one means which may be used for doing this is disclosed in Fig. V; wherein I show the yarn guide ring 48 as secured to a shaft 49 journaled in bearings at the ends of posts 50 projecting upwardly from the bed plate 2 of the machine. To one end of the shaft 49 is secured a spur pinion 51 which intermeshes with a gear sector 52 loosely mounted upon a stud 53 projecting from a suitably disposed extension of the bracket 3. The gear sector 52 is formed with an arm 54 which carries an anti-friction roller 55 operating in a cam slot 56 in a supplementary cam drum 57.

The action of the cam slot 56 upon the roller 55 is such as to swing the yarn guide ring 48 upwardly and out of the way. S111} plementary cam drum 57 is preferably driven from the cam drum 12 by means of intermeshing spur gears 58.

In Fig. VI, I have illustrated another i'neans for moving the yarn guide ring 48 out of the way. In this instance the ring 48 is secured to a hollow stem 59 vertically movable upon a post 60 projecting upwardly from the bed plate 2 of the machine. This construction requires the use of the gears 51 and 52 and cooperating parts described in the last paragraph in connection with Fig. V. Movement of the cam 57-as before desrribedrocks the shaft 49, and in this form said shaft is provided with a supplementary spurpinion 61 intermeshing with a rack 62 formed on the hollow stem 59. As the pinion 61 is rotated it raises the stem 59 consequently lifting the yarn guide ring 48 vertically out of the way.

In Fig. V, I have illustrated a construction that may be used when my invention is to be applied to a knitting machine having a dial. In this view a ribbing dial 63 is shown as driven by a central shaft 64 which receives its motion from a transverse fer rin o shaft 65 through the medium of bevel gears 66. The shaft 65 is-in turn-driven by a vertical shaft 67 through the medium of bevel gears 68, and said shaft 67 is driven, in any suitable manner, from the main driving shaft of the knitting machine.

A supporting frame 69 for the ribbing dial 63 and the shafts '64 and 65 is mounted upon the upper face of the yarn guide ring 48; and when said yarn guide ring is swung out of the way, the ribbing dial 63 with its driving mechanism accordingly moves with it. As it is necessary, when the ribbing dial 63 is returned to place, that its parts be in. absolutely the same positions they occupied before said dial was swung upwardly, I provide for this purpose a locking mechanism which comprises a spring pressed lever 70 fnlcrumed upon the supporting frame 69 and normally hearing at its outer end against the upper end of the vertical shaft '67. As soon as the yarn guide ring 48 and ribbing dial 63 begin to move out of the way, the lever 70 is pressed by its spring and enters the notch 71 of a disc 7 2 which is fixed on the shaft 65, thereby locking the latter against rotation and preventing movement of an of the parts of the ribbing dial 63. When the ribbing dial 63 is returned to the normal position shown in Fig. V, the outer end of the lever 70, at the terminus of the swing, strikes against the upper end of the vertical shaft 67 and is lifted out of the notch 71, thereby releasing the parts while the 68 are brought into mesh.

The same construction isapplicable to a welting dial, and either dial may be mounted upon the yarn guide ring 48, as shown in Fig. VI. In this case it would not be necessary to provide locking means for the driving gear inasmuch as the gearing could be so mounted as to ride with the dial without any disengagement of elements.
